Hi,
transconductance is not constant.
It varies with current (Id).
Look at the graph in the datasheet.
It varies from 0 @ 0mA Id through 20 @ 2mA ID to 40 @ 10mA Id.

Hi,
sorry for being not perfectly clear: I mean constant for the same current.
Since this is exactly what one does by increasing the source resistor; one adjusts the higher current of the BL-parts to the same, lower current. So for the same current they (BL vs. Gr) have different source resistors, but the same transconductance, no?
I hope I was more clear this time!
All the best, Hannes

Back!!
I already reserved it for more than 1000 pieces of both JFET's, and i thought after this, i will stop a GB and sale it in trading post section.
Do a GB is not an easy task especially for hard to find parts, many mails to reply, many question to answer, many problems with payments, so to you all folks, please be patient... 🙂
my estimate time for shipping is early december, and to all buyer, please bounce me an email if you already receive the package later.
i want to finish this GB with smooth and esp the fair price 😎
if you wanna look for other hard to find parts, dont hesitate to mail me, i do my best to help.
Have a nice weekend!!!
all the best,
a'af

Hello
I don't know if is too late to buy 10 sj and 10sk.
Could you please answer me.
Thank you very much
MALZA 😉 😉

About a week this GB will closed
To all folks i will announce, about a week I will closed this GB, so no more order here, so if somebody still want this nice JFET's pls make your order asap, i will never reply any mail about request or others after i really close this GB, just confirmation to all buyer who already paid, Thanks to all who already join in this GB, your patient and kindness is more valuable for me to do this "HARD JOB" 😀
as my previous post, this will start to ship in early december before the traffic of post is jammed cause christmas and new year venue, but this very tentative, if post office too crowded, for safety reason, i will ship after that, hope this can be understandable to all 🙂
Thanks to you all...

Last chance ?
Hello A'af
is it too late for me to place an order : I'm interested by 10 x 2SJ109 plus 10x2SK389 ?
I'm sorry about the late answer.

Hello A'af
I've know that it is late but if it is posible i've would like 12 x 2SJ109 an 4 x 2SK389 ?

Group Buy are CLOSED
Hi again folks,
sorry to announce this GB is closed, we already reached 1000 pieces for both of this JFET's
but my source say is ok for me, to sell at least 100 pieces but with the higher price!! and after i calculate it, then the price is NOW is US$8 / each
so for the late order or somebody wants more...
YES I can help you to buy this, but just for minimum order of 10 pieces per order, and i also dont know how much pieces this supplyer have in their stocks, instead 1000 pieces in single order!
and after this, i will very busy to completed this GB just by myself alone!! confirmation and packing and sending!! 😉
so please be sorry if i very slow in reply and else.
Thanks for all to make this GB success!!
all the best,

An OT question..Pin 4 on 2SK389,is it NC or?

Ryssen,
read what Mr Hansen has to say about the plastic duallies.
Before its too late...
Hi again,
shipping is around, for who wants change the address or want when exactly the package will arrived, please mail me 🙂
for example, change to office address or sister address and want receive it after christmas or new year, i can keep it for you... 😉
for the late request and new buyer and also for members who want more, pls let me know... will wait till end of december
your attention about this will help me a lot!! 😀 thanks all 😎
